BARREL-8G MACHINE.

Application and April 25, 1921. Serial no. 464,075.

To all whomz't may concern! Be it known that I, Bnon J. LINDGREN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New 5 York, have invented new and useful Iniprovements in Barrel-seaming Machines, of which the following is a specification.

This invention relates to a machine forforming seamed joints between the body and heads of a sheet metal barrel or cask and has for its object the production of a' machine for this purpose whereby the seaming operations may be effected efiiciently and expeditiouslv and the working parts may be quickly and easily adjusted to suit barrels varying in length and diameter, as well as varying in the form of the seam, and also to permit of readily taking up wear and effect necessary adjustments when assembling the machine ready for operation.

In the accompanying drawings: Figure 1,

is a fragmentary side elevation of a duplex double seamer for double seaming both ends of a sheet metal barrel or cask at one opera '25 'tion. Figure 2 is a vertical 'transverse'section of thesame, on an enlarged scale, taken on' line 2--2, Fig. 1, but showing the barrel whichis being seamed in dotted lines. Figures 3, 4 and 5 are vertical sections taken on 0 the correspondingly numbered lines in Fig. 2. Figure 6 is a horizontal section taken on line 6-6, Fig. 4. Figure 7 is a perspective view of one of the seaming tools or rolls and associated parts in a dismembered condition. Figure 8 is a similar view of one of the spindles. supporting a seaming roll and as sociated parts. Figure 9 is a fragmentary sectional view showing the' drum or bod and the head of a barrel mounted on a chuc 4 preparatory to seaming them together. Figures 10 and 11 are similar views showing the successive operations of curling together the co-operating flanges of the drum andhead and then tightening the same by means of ste in the operation of seaming the hea the seaming rolls. Figure 12 is a fragmentary longitudinal section, on an enlarged scale, of the mechanism for shifting the movable standard for gripping and releasing the barrel which is being seamed. Figures 13 and Marc vertical sections, on an enlarged scale, of the valve which controls the movement of pressure medium to and from opposite ends of the cylinder of the standard shifting mechanism. I

Similar characters of reference indicate 20 of sheet metal, and two disk-shaped,

the adjacent flange of the; drum engages its corresponding parts throughout the several views. y

The barrel or'cas'k which is to be operated upon by my improved seaming machine, for connecting the drum and heads thereof, may be variously constructed but the barrel shown in the drawings as an example of one capable of being produced by the machine comprises a cylindrical body or drum heads 21 of sheet metal secured to opposite ends of the drum. The drum is provided at its opposite ends with integral laterally extending flanges 22 "and each of the heads is provided at its ed with an outwardly projecting annular mm 23 which is connected integrally at its inner edge with the head, and an annular flange 24 rejecting laterally from the front edge 0? the rim and formed integrally therewith. In the o ration ofseami the drum and heads 0 a barrel, each hea is placed on the support-in ring 25 of a rotary chuck sothat the front ace 26 of the ring bears against the outer side of the head and the periphery- 27 of the same bears a' ainst the inner side of the rim, and the is engaged on the inner side of each end with the outer side ,of the rim of one of the heads while outer side with the inner side of the flange of the respective head, as shown in Fig. 9. After the'drum andheads have been thus asembled and the same are rotat' about the axis of the barel, both ends fi the latter are presented to two primary or preliminary seaming rolls 28 each of which is provided on itsperiphery with a. preliminary seaming groove 29 which is adapted to rotate in engagement with the flanges of the drum and head at one end of the barel and produce a preliminary curl or partial interlock of the same, as shown in ig. 10. After the first or prelimina no an druin of the barel together has been 'acomplished, and while the barrel is rotat ing with the chucks, the partly seamed flanges of the drum and heads are engaged by the final or finishing grooves 30 on the riphe of two final or finishing seaming rolls 31, which rotate in engagement with these flanges and operate to press the same flat andcause the same to engage firmly with each other andfinish the interlocking engagement of the same, as shown in Fig: 11, and produce a tight joint therebetween. In its general organization, the machine which embodies the means for rotatably supporting the barrel and operating the seaming rolls is constructed as follows:

The main frame of the machine comprises a horizontal base 32and two standards 33,

lid

31, mounted on the front and rear ends of the base. The front standard 33 is preferably fixed on the base while the rear standard 34 slides at its lower end on a guideway or track 35 upon which the same is movable lengthwise of the machine to permit of adapting the same to the manufacture of barrels of difierent lengths. 36, 37 represent front and rear chuck shafts or spindles which are aranged horizontally and length wise in line, the front shaft 36 being journaled in a suitable bearing in the lower part of the front standard and the rear chuck shaft 37 being journaled in a suitable bearing in the lower part of the rear standard but held against lengthwisemovement therein, for instance, by a collar 371 secured to the adjacent part of the rear standard and engaging with a circumferential groove 372 in the rear chuck shaftpas shown in Fig. 12. Each of these chuck shafts is provided at its inner end with a chuck disk 38 upon which one of the supporting rin 25 is removably supported by engaging t e latter with an annular rabbet-sha d seat 39 on the periphery of this disk, said ring and disk together formin the main elements of a chuck for rotataly supporting one end of a barrel.

40 represents the main driving shaft of the machine which is journaled horizontally and lengthwise on the base and provided with front and rear pinions 11, 12, which mesh with front and rear gear wheels 413, 141,

' on the outer ends of the chuck shafts 36, 3?.

The driving shaft may be operated by power from any suitable source with which the same may be connected by any aproved or usual clutch or coupling evice. llhe front chuck shaft and the parts mounted thereon are held against longitudinal movement. The rear chuck shaft is however capable of longitudinal movement for the the chuc mounted thereon. and permitting the barrel to be seamed to be clam wl between the front and rear chucks w ile effecting the seaming operations thereon and to release the same after the seaming opera tions have been completed. This advancing and retracting motion of the rear standard, chuck and chuck shaft may be accomplished by any suitable means but preferably by a fluid omrated motor which is constructed and operated as follows:

represents a shifting cylinder which mounted lengthwise in the lower part of the urpose of advancing or retracting P resume rear standard so as to move therewith and having ports 106, 107 in its front and rear heads. 108 is a stationary piston arranged within the shifting cylinder and secured to thefront end of a piston rod 109 which extends through a stnfing box in the rear head of the shifting cylinder and connected at its rear end with a bracket 110 which forms part of the stationary'frame of the machine. 102 represents the casing of a four-waycontrolling valve whereby the entrance and exit of the pressure fluid to and from opposim ends of the shifting cylinder is controlled. This casing has front and rear delivery ports 111, 112, a supply port 113 and an exhaust port 114 arranged equidistant about its center and connected respectively with a pipe 115 leading to the front port of the shifting cylinder, with'a pipe 110 leadin to the rear port of the shifting cylinder, wit a pipe 117 leading to a source of supply of pressure medium, such as water under pressure, and

with a waste-pipe 118 leading to a sewer or other convenient place. Within the valve casing 102 is arranged a rotary plug 119 ternately turning the plug of the controlling valve in OEPOSNE directions the shifting? cylinder an the rear chuck and associated parts operatively connected with this cylinder will bemoved forwardly and backwardly so as to grip the barrel to be seamed betwmn the chucks and to release the same after this seaming operation.

Any suitable means may be provided for operating the controlling valve, those shown in the drawings being suitable and comprising a valve shaft 120 arranged lengthwise on one side of the base of the frame and journaled in suitable bearings on the same andprovided with front and rear rock arms 121,

122, a rear intermediate elbow lever 123 ivoted on' the rear part of the base and having its lower arm connected. by a link 1% with the rear rock arm 122, a valve arm 125 connected with the. stem 126 of the valve lug 119 and connected by a link 12? with t e u per arm of the elbow lever123, and a ban operated 'front elbow lever 128 pivoted on the front part of the base and aving its lower arm connected by a link 129 with the front rock arm 121, as shown in Figs. 1 and 2. Adjacent to the hand lever 128 is arranged another band lever 130 for operating the clutch 131 which couples and uncouples the driving shaft 40 and the driv ing means in any approved or usual man ner. This. valve mechanism is organized that the water or other pressure medium continues to press the rear standard forwardly and hold the rear standard against the barrel during the operation of seaming the same and thus insuring the rotation of the barrel. but after the controlling valve is reversed manually, the water pressure will first move the rear standard backwardly to release the barrel and thereafter the plug of the controlling valve will be automatically shifted into its central position so as to cut off the pressure medium from. both ends of the shifting cylinder and thus bring the rear standard to a standstill. This automatic shifting of the controlling valve plug into its neutral position is due to the fact that this valve moves rearwardly with the rear standard while the intermediate rock lever 123' for the time being is stationary, thereby causing the link 127 which acts as an abutment to gradually turn the controlling valve plug from its rearwardly turned position, in which the pressure water moves the rear standard backwardly, to its neutral position, in which the pressure medium is cut off from both ends of the shifting cylinder.

In order to permit the rear chuck shaft to move lengthwise and still maintain a driving connection between the same and the rear gear wheel 44, the latter is splined on the rear chuck shaft and journaled on an adjacent block 45 of the base so that this gear wheel is free to turn but heldagainst moving lengthwise with the rear chuck shaft.

Adjacent 'to the inner side of the upper part of each standard are arranged one of the preliminary seaming rolls 28 and one of the finishing rolls 31. these rolls being arranged above the adjacent chuck and in spaced,' relation circumferentially' of the same, so that these rolls may engage independently of each other with the flanges of the drum and head on the corresponding end of the barrel for producing the successive operations to curl and finish the seam joint on the respective end of the barrel.

Each of these rolls. is so mounted tha the same is moved periodically toward and from the flanges *on the respective ends of the barrel and the same is also capable of bodily adjustment both radially and also lengthwise of the axis of the barrel for adapting this roll to the flanges of the barrel, to permit of seaming of barrels of different lengths and also to originally adjust the machine and also take up wear in the same. In its preferred embodiment the mechanism whereby this is accomplished is constructed as follows:

46' represents a main slide which moves radially in ways 47 on the inner side of the. upper part of each standard, the slides of the of cams 48. 49. which engage with antifriction rollers 50, 51 on the upper ends of these slides. respectively, and which are mounted on cam or seamer shafts 52, 53, journaled horizontally and lengthwise in hearings on the upper parts of the standards. The cams next to the front standard 33 are secured to the cam shafts but the cams next to the rear standard 34are splined on the cam shafts, so as to turn therewith but the same are" compelled to move lengthwise on these shafts with the rear standard when the latter is moved lengthwise of the ma-. chine. Mot-ion may be transmitted to these cam shafts in any suitable manner, this being accomplished for example by the means which are shown in the drawings and which compriseacounter or jack shaft 51: journaled in the upper part of the front standard between the cam shafts and provided with an intennediate gear wheel 55 meshing with gear wheels 56. 57, on the cam shafts, an upper. intermediate shaft 103 journaled in the front standard and provided with a pinion 58 meshing with a gear wheel 59 on the counter shaft, and a lower intermediate shaft 60 journaled in the front standard and provided with a pinion 61 meshing with a gear wheel 62 on the upper intermediate shaft and also provided with a gear wheel 63 meshing with a pinion 64 on the companion chuck shaft, as shown in Figs. 1, '2 and 3.

The return or outward movement of each main seaming roll slide is effected by a retracting spring 65 arranged in a pocket 66 in, the adjacent part of the respective standard and bearing at one end against the bottom of this pocket and its other end against a lug 67 on this slide. said spring be- .ing held in position by'a retaining rod 68 passing through said spring and secured at one end to said lug whileiits other end is guided in an opening 69 in the bottom of said pocket.

Upon each of the main slides is mounted a carrier or holder upon which is adjustably and rotatably supported one of the seaming rolls. This carrier is preferably of inverted U-form having front; and rear arms 70. 71. the rear arm being provided with a dovetail guide ribj 72 which engages slidingly with a correspondingly-shaped guideway 73 on the outer sideof the companion main slide 46. Adjustment of the carrier on its main slide is efiected in a radial direction relative to the axis of the chucks by means ieo of an adjusting screw 74 engaging withits intermediate part with a threaded opemng in the carrier while its ends are journaled on the main slide, so as to. be capable of turning thereon but compelled to move radially therewith. Each of the seafming rolls is arranged between the front and rear armsof one of the carriers and journaled bearing rollers between this roll and the,

axle .and which engage with the outer and i-nner'shoulders 81, 82 formed on the axle between the enlarged central part and the reduced end parts thereof, as shown in Figs. 4 and 6. The front end of each roll axle is arranged in a front bushing or sleeve 83 which has a smooth periphery and is capable of turning and sliding lengthwise in a smooth bored opening 84 in the front arm of the respective carrier, and the rear end of this axle is arranged in a rear bushing or sleeve 85 which latter has an external screw thread 86 engaging with an internally threaded opening 87 in the rear arm of the" respective carrier. The front bushing and retaining disk are compelled to turn together by coupling lugs or keys 88 arranged on the front side of the front disk and engaging with recesses 89 in the rear end of A the front bushing, and the rear disk and bushing-are compelled to turn together by coupling lugs 90 arranged on the rear side of the rear disk and engaging with recesses 91 in the front end of the rear bushing. The latter is also coupled with the axle so as to be compelled to turn therewith by a key 92 arranged on the rear partvof the axle and engaging with a recess 93 in the bore 1 of-the rearbushing. On the front end of the front bushing and the axle is mounted an adjusting disk or wheel 94 which is connected with the axle by a screw '95. The wheel is provided on its inner or rear side with a diametrical groove 96 which engages with coupling lugs 9? on the front end'of the axle and coupling lugs 98 on the front end of the front bushing. By means of this construction a turning movement of the wheel 94: in either direction will, cause-the axle, seaming roll and the other parts mounted thereon to 'move either forwardly or backwardly as a unit and thus permit of adjusting the seamingroll to the required position for properly operating on the flanges of the head and barrel for producing a seamed joint between the same, while.

at the same time preserving the proper condition of the beari for the seaming roll,

inseam so as to enable the same to operate most eficiently and accurately.

For the purpose of retaining the seag roll in its adjusted position, a locking device is provided which preferably consists of a locking catch 99 guided in a'lug, 100 on the front side of the respective carrier and held by a-spring 101 yieldingly in pngagement with one oranother ofan annular row of notches 104 in the'peripheryof the locking wheel, as shown inhigst 2 and 4t.

The operation of seaming a barrel is as follows:

The operator places a barrel dr and its heads, which have previously been 'assembled, between the two chucks and then operates the controlling valve, so as to cause the rear chuck to advance and clamp the barrel between the front and rear chucks, and thereafter the barrel will begin to rotate, inasmuch as the chucks rotate constantly while the machine is in operation. Tmmediatelythereafter .the cam shafts on the front and rear standards begin to rotate. These cam shafts are so timed that the cam shaft of the preliminary seaming rolls causes the cams thereon to first depress both of these rolls and hold thesame in thisposition a sufiicient length of time to enable these rolls toiefleet the preliminary seaming or curling'of the drum and head llanges at both ends of the barrel in the manner indicated in Fig. 10. The preliminary cams then permit the return springs of the pre liminary slides to retract the latter so that the rolls thereon are disengaged from the barrel flanges, after which the finishing cams adjacent to both standards cause the slides of the finishing rolls to depress the latter into engagement with the flanges at both ends of the barrel and retain the same in this position a suficient length of time to enable them to'complete the formation of the seams thereon, after which the slides of the finishing rolls are again retracted for carrying the same into their inoperative position. The cycle of operations is now completed and at this time the rotation of the scanner cams is preferably arrested automatically by any suitable or approved means usually employed for this purpose in this type of machine. The finished barrel is now, removed from the chucks and replaced by an unseamed' barrel preparatory to etl'ecting another cycle of operations.

This machine permits of efiecting the seaming of barrels in this manner expeditiously and eficiently and the same can be readily adapted for seaming barrels of various lengths and diameters and thereby enables barrels or this character to be produced at comparatively low cost M I claim as my invention: 7
